Daehyun was staring at Hyosung who was standing outside their classroom. For the past few days, he noticed something odd about her. She's been staring off to space and wasn't the gummy-smiled girl he knew. She doesn't tell him anything at home too. After dinner, she locks herself in her room. Whenever he asks, she always answer's the same thing "I just miss umma". He suddenly walked  towards her and grabbed her hand, leading her to the chemistry lab.

"What is it.?" Hyosung asked him as he closed the door

He looked at her for a moment "I know something's bothering you. Tell me"

"I already told you. I just mi----"

Daehyun cut her off. "It's something else. I can see it in your eyes"

Hyosung stared at him and hugged him. "It's nothing really. I just miss my umma. That's all". She was about to burst in tears but stopped herself. She caressed his cheeks and tried her best to smile "Trust me. I'm fine" 

After eating lunch, Hyosung and Jieun headed back to the classroom to get her English notebook that Zinger wanted to borrow. When she got the notebook, a little note dropped on the floor. She picked it up and read the message on it

"Let's meet at Room 319 after lunch today. Just the two of us  ~ Hyuna"

Jieun read the message and looked at her worriedly "Don't go Hyosung-ah."

"I have to. I need to finish this" she said

"No. I'll go with you" Jieun protested

She looked at her bestfriend and smiled "I'll be fine. I promise. And don't tell Daehyun and the others. Cover up for me"

Hyosung was walking alone to the room that Hyuna said. She opened the door to see her sitting near the window

"What is it now Hyuna.?" she asked

"I wanted to finish what I started the last time"

"I'm not leaving him Hyuna. We love each other" she said

Hyuna groaned "He doesn't LOVE you. He should ONLY LOVE me.!"

"He LOVES me"

"He DOESN'T.!"

"Yes HE DOES.! Why is that so hard for you to accept.?!"

"Because he's MINE.! MINE.! MINE.!". Hyuna couldn't take it anymore, she pushed Hyosung down the floor and started strangling her

Meanwhile in the cafeteria. Jieun was worried at what was happening with Hyosung and Hyuna. She kept looking at the cafeteria door, hoping to see Hyosung walk-in anytime "Hyosung-ah. Are you okay.?"

Yongguk noticed the worried look on her face. "Are you okay.? You look worried."

"Is something bothering you noona.?" Zelo asked

Youngjae took a sip of his cola and looked at her "By the way, what's taking Hyosung so long. I thought you said she just went to the library to return a book"

Jieun couldn't take it anymore. She stood up from the table, surprising her friends. "I can't take it anymore.! Daehyun-ah..! The thing is, Hyuna was the one who spread the rumors about you and Hyosung's relationship. Last time, she slapped Hyosung in the girl's restroom and told her to leave you. We were going to tell you but Hyosung said not to. And so, right now at this very moment. Hyosung and Hyuna are having a talk at room 319 and I'm very worried on what's happening right now. I'm worried that Hyuna might hurt her again" she said out of breath

All of them were obviously shocked from what Jieun said. Suddenly, Luna ran towards their table.

"Jieun unnie. Hyosung unnie is in trouble. We can't stop Hyuna.!" she panted

Daehyun's eyes widen and quickly ran outside the cafeteria with the other's following him.

"Hyuna.! Get off of Hyosung" Jaekyung said as they tried to grab her away from Hyosung

"Let me go.! I'm not gonna leave her until she stays away from my Daehyun oppa" she shrieked in anger

Hyosung was crying on the floor and stood up "I-I'm not gonna leave him Hyuna"

"Aaaaahhh.! You slu---.!" Hyuna said. As she was about to grab her hair, a hand yanked her away.  She turned her head to the side to see an angry Daehyun glaring at her.

Daehyun stood infront of Hyosung and looked at her. "Jieun-ah, get Hyosung" he said. Jieun ran to Hyosung and stepped her to the side.

"Omo noona, you have a scratch on your arm" Jongup said worriedly

Sunhwa rushed to her side and looked at her arm "Let's go to the nurse's office

"I'm fine you guys" she assured them

Daehyun faced Hyuna and glared at her. He stood infront of the teacher's table and angrily punched the table, scaring the student's surrounding the room. "Nobody touches my girl.!!"

Hyuna looked at him, scared. "O-oppa"

"Don't call me that"

"I love you oppa.! Why can't you see that.?! Are you really that blind to not notice how inlove I am with you". She said as cried.

Youngjae stepped in the scene and sat on a chair. "That's not love Hyuna-shi. You just hurt the most important girl of the White Prince and you said that you're inlove.? That's obssession Hyuna-shi"

Hyuna looked at Youngjae in disbelief. "N-no.! I love him.! I do.! Everything was perfect until that came into picture" she pointed to Hyosung

Daehyun got really angry as he heard the word "" . He kicked the teacher's table and walked closer to Hyuna. "Don't you dare call her that.!"

Hyuna hugged him. "Yes she is. If you leave her, you'll be much happier with me oppa"

He pushed her to the floor and dusted off his clothes. "You look pathetic"

Hyuna turned her head to Hyosung. "Look what have you done.! You brainwashed Daehyun oppa. You're such a .! .! .! Slluuuttt.!"

Daehyun grabbed Hyuna by the neck and pushed her on the wall."Shut your f---ckin mouth or I'll shut it for you"

Zelo gasped and looked at Yongguk "Hyung.! Stop Daehyunnie hyung. He's getting w-wild.!"

"Nobody can stop him. . Except . . . . " Yongguk said as he glanced at Hyosung who was watching the scene

Daehyun let Hyuna go and smirked behind his mask. "You have no idea what you just got yourself into". He started  walking back to Hyosung when Hyuna said something that made him explode.

"What's so good about her anyway.?! I'm much prettier than her.?! Is it because she's rich.?! You're already rich oppa. What you need is someone like me. Popular, pretty, y and 100000 times better than her.!"

He stopped in his tracks and knuckled up his hands. He turned around to slap Hyuna when someone from behind hugged him.

"Stop it Daehyun-ah. Stop it" Hyosung whispered, tears flowing down her beautiful face.

As she let go from the hug. Daehyun kicked the tables and chairs that were surrounding them. "Everyone in this very room.! If you ever lay a finger on my girl, I would so look for you in the depth of the sea and feed you in the sharks.! Never mess with Jung Daehyun's girl.! Especially you.! You disgust me.!" he said as he pointed to Hyuna. He grabbed Hyosung's hand and walked out of the room.

The whole ride home was silent. Daehyun didn't say a word and didn't even eat dinner.

"Noona, did something bad happened at school.?" Yi Jung asked

Hyosung smiled at him "No. Your hyung is just tired"

"It's okay if you don't tell me. But whatever it is, you should fix it" he said

She dropped the spoon from her plate and groaned. "Aaaahh.! I don't know how"

Yi Jung shrugged "Just tell him everything. Hyung doesn't like it when you lie or keep secrets from him"

"Gomawo for that Yi Jung-ah"

After dinner, Hyosung was standing outside Daehyun's door, walking back and forth. She knocked on his door and decided to go inside when she heard no response. She found him laying down on his bed, his back facing the door. 

She lay down next to him. "Daehyun-ah. I'm sorry I didn't tell you."

Still no response

She bit her bottom lip and poked his shoulder "Baby-ah. Talk to me please"

"Why didn't you tell me.?" he asked, his back still facing her

"I didn't want you to worry" she said

"And look at what where it got us. I'm still f---ckin worried and pissed.!"

Tears were slowly blurring her eyes. "I-I-I'm so-sorry. I didn't mean to"

Daehyun sighed and turned to face her. He s his left arm under her neck and hugged her. He could feel warm water hit his chest but he didn't mind. He slowly rubbed her back and sang a song:

 I don't know the reason why I changed

 I've been thinking for a long time,

 With many dificulties ahead

 I seem to be changing quite a lot,

 Please end this. Oh

 Can you hear this song.?

 Thank you. Oh baby

 You're so pretty. Oh

 There's not a thing that can stop me from looking at you

 Only you I continuously see. Oh baby

After singing, he can no longer hear her cries. Hyosung wrapped her arms around his waist and closed her eyes. "That was beautiful"

He kissed the top of her head and hugged her tighter. "Let's sleep"

(Aaaahh.! I really love Daehyun's cover of Baby Baby. He's voice is so soothing. And I'm sorry I turned Hyuna to an obssessive character ^_^)
